Make delegate dependency locking lock contracts and not code hashes

[athei]

On EVM delegate calling another contract ins infallible because code cannot be deleted. In our system contracts and code hashes can be deleted. This is why we allow for code hashes to be locked in place for a deposit.

With the introduction of immutable variables delegate call depends on a contract and not a code hash anymore. This is because they need to read their immutable data for execution.

We need to update the locking system to allow for locking of contracts and not code hashes.

Pre-compile support is needed to expose this additional functionality.
